🌱 How to Care for Black Magic Alocasia to Prevent Sunburn (Sun Scorch)?

💧 How to Water

From spring to autumn, water when the top 3-5 cm of mix is dry, then let the excess drain away. In winter the plant slows down: water only enough to keep the roots from drying out completely. Soggy soil, especially in winter, rots the roots.

☀️ Lighting

Bright but indirect light, such as near an east window or a few steps from a sunny one. Direct sun scorches the dark leaves. In low light it survives but grows very little.

🪴 Ideal Soil

Light, airy, well-draining mix, for example houseplant compost or peat with plenty of perlite or grit (about three parts mix to one part grit). Avoid heavy soil that stays wet.
